a random drug test yielded a positive test for methadone. If you are not taking methadone, how could that be?

Methadone is a synthetic opiate and it is possible that on a test that isn't done by a certified lab, other substances could cause you to show a false positive for it, including other synthetic or semi-synthetic opiates.

Few employers are required to use a certified lab and most of the regular, inexpensive labs do have an error rate that ranges fro 4 to 50%.

Sharron, in your case, it could have been the NyQuil, as it has been known to cause a false positive for Methadone on these types of tests.

It may also cause false positives for Amphetamines, Heroin and Meth.


cycleman, have you been taking anything else, including over the counter products?

i an extremly upset. I went to the doctor today and he accused me of a dirty urine having methadone in it. I have never even seen a methadone pill. I told him I am taking nucenta 75 mg. could this have registered as methadone. I am extremly hurt. I have been accused of being a liar and druggie.

Ramona, Nucynta contains Tapentadol and it isn't know to cause false positives, so far, but from the various posts we've gotten on them, from all different classes of medications, I can't say that anything really surprises me, anymore.

There are, apparently, some bad tests on the market, that are causing all manner of odd results.


And also, I'd like to ask if you were taking anything else, even over the counter products?

Hi, I took a 15 mg dose of methadone on Friday at 4 pm. I dont take it every day. I have a pre employment drug screen today (Monday)... Will it show up on a 10 panel since it was a low dose and I don't take it every day? I do take allergy meds, lortab (legally) and Nyquill regularly

I know what you mean. i had an accident at work and had to take a drug test and it came back positive for methadone. I did't know what methadone was until the the nurse told me at the Drs. office told me. I never taken methadone, never had a prescription for it and now I don't have a job. I feel like people think i am lying. Does anybody know of any type of drugs that could cause you to have a false positive drug scheening for methadone. Thanks

I just got a positive lab test for methadone but I have never taken the drug before. I am in a treatment center that gives me meds daily and it has been showing up since I got here. My probation officer thinks i am getting this drug in my treatment center illegally somehow and this is impossible. I am currently taking sertraline, propanolo, oxcarbazepine, trazodone, cetirizine and buspirone. Can any of these or a combination of these cause a certified lab to falsely test urine for methadone?

I have been in recovery court for a year and half for drinking. I test 1 to 2 times a week and never droped dirty untill about 2 to 3 weeks ago. I have tested posititive for methadone on the 10 panal strips 3 weeks in a row at testing once a week. They labed the first one and came back positive. I have never done methadone in My life and didn't know really what it was untill I tested positive. The only thing I have done diffirent in the last year and a half is start taking birth control, wellbutrin and Ibuprophin 800 (IB p I took the whole time). The positive tests started as soon as I started taking them. I have not taken any other drugs. What could cause me to lab test positive for methidone 3 weeks in a row? It is driving me crazy to know I haven't ever in My life touched it and people think I'm full of s***. Honestly... that's what I would think. Pleas help!!!

Today my husband went into the dr o manage his seriouse neck problem and he is prescribed Percocet 7.5MG and they gave him a urine test and he tested positive for methadone, but he took only one pill 5 days prior to ehs appointment, due to serious debilitating pain and then he took sudifed PE and ibprofen for the cold he had 3 days prior to his appointment, could he just recieved a false positive from that??? I really doubt he had any methadone in his system he has such a high matabolisum, and works, eats and drinks lots of water daily. They sent the test out to be tested at the lab and I would hate to see him not get treated because of a over the counter medication. Can they tell exactly what medication it is? or is it just a catagory they use to put the nmedications in?d

I went to my doctors appointment for maintenance. I have been on suboxone for years and have stayed clean for years. About two months ago they came out with a generic suboxone so I started taking that. My copay went from $50dollars to $10. Well much to my surprise the doctor took a urine sample and I tested positive for suboxone and methodone. I have never taken methodone in my life. I felt like know one believes me. It brings back so many bad memories of the addict I once was. The lying, stealing and cheating. But I took another urine test and still positive for methodone. So I decided to go to lab cor and get a blood test. My doctor will get the results Monday or T Tuesday. It's a terrible feeling to know your telling truth and can't prove it. But I swear I have never ever taken methodone. Please help me understand this ??? Any idea's ???
